Daconil Fungicide Liquid Mixing Instructions

Daconil fungicide controls various fungal diseases including anthracnose, leaf spots, blights and rots on many different species of plants. This readily available fungicide contains the active ingredient chlorothalonil, which is a broad-spectrum substance that can be used on ornamental plants as well as vegetables and fruits. The amount of fungicide used will depend on the plant as well as the fungal disease you are trying to manage. That is why it is vital you follow the specific instructions on the label.

Ornamental Diseases

1

Fill a bucket with 1 gallon of water. Add 2 1/4 teaspoons of Daconil fungicide concentrate to the water and mix thoroughly. Pour the solution into a clean garden sprayer.

2

Spray the foliage of the diseased plant with the diluted fungicide to the point of runoff.

3

Repeat the treatment at intervals of seven to 14 days until the disease is gone.

Vegetable Diseases

1

Dilute 1 1/2 teaspoons to 1 tablespoon of Daconil fungicide concentrate in 1 gallon of water. The amount of fungicide depends on the vegetable infected and the fungal disease causing the infection. For example, 2 teaspoons of concentrate fungicide mixed with 1 gallon of water will control blight on carrots.

Transfer the solution to a pump spray and cover the leaves of the vegetable until the solution begins to drip off the foliage.

Reapply a fresh solution every seven to 14 days as needed.

Fruit Diseases

1

Mix 3/4 to 2 1/4 teaspoons of concentrated Daconil fungicide with 1 gallon of water in a bucket. The exact amount of fungicide used varies depending on the species of fruit and fungal disease. For example, 2 1/4 teaspoons of the fungicide diluted in 1 gallon of water will control leaf curl, blight and brown rot in peaches, cherries, plums and apricots.
